Dustin,

When you add a handler you may specify an identifier so that
you can address a specific instance of a handler:

   gen_event:add_handler(temp_listener_events, {lemp_handler, 1}, Args)
   gen_event:add_handler(temp_listener_events, {lemp_handler, foo}, Args)

   gen_event:which_handler(temp_listener_events).
   [{lemp_handler, 1}, {lemp_handler, foo}]
